This invention relates to containers, particularly of the wide mouthed type, and closures therefor. It has for its main object the, production of a jar adapted for commercial display as well as for domestic use, and, in respect to the closure, provided with a cover possessing distinctive efiiciency, novelty and utility in difierent degrees as occasion may demand. V

What constitutes my present invention will be hereinafter described in detail and'su'ccinctly defined in the appended claims.

- Referring to the numerals on the drawings, 1 indicates a container body. which is 'preferablymade'ofglass, having a wide an.-

nular mouth-defining rim 2 that preferably project's outwardly about the mouth of the container so as to demark a circularneck'3, defining in therim above the neck a con- 1tinuous annular retaining ledge 4.

Theledge' maybe disposed substantially at right angles to the outer perimeter of the rim 2, or it maybe disposed at aslight deviationsfrom a right angle, asindicated at 5 in Figure order to coactivelyadapt it Figure VIII illustrates a modification of 1931. Serial n 520,145.

for thespecific form of latch member shown in FigureX as well as shown detachedly in Figure VIII. a r i A. cover comprising preferably a circular, disc-shaped cap plate 6', made integral with an annular periphericalskirt'7, is provided as a closure for the container mouth which the rim 2 defines, as aforesaid.

The-cover. is, for the sake of desirable economy of manufacture, conveniently made 5 ofthin sheet metal, despite the fact that,'in itself, it affords little resistance .to any force tending to bend or warp it. That feature in itself would be'objectionable in use, but'I practically eliminate it by providing upon oppositesides of the cap plate 6 reinforcing plates 8 and 9 that are firmly secured to. it 7 as by strong through going rivets 10 which hold said plates in close juxtaposition against the upper and lower faces, respectivelyyofm thecap plate. 'Thus, the plates 6,8, and 9 are economically united into one composite 'cover that is by the reinforcing plates made stifi enough to resist any force whiohin ordinary use might tend to warp it.

In'addition to and in aid of thereinforcing function of the plates 8 and 9, .the former, as by aid of lateral infolds 1'1 and 12, pro vides means for securingto the topof the cap plate 6 legs l3 and 14:, respectively, of a distinctivelatchmember 15 {and thelatter 1' provides on its perimeter "an annular flange 16; Saidfiange is uplifted slightly from the surface of the inner face of the cap plate 6 so as to cause it to combine therewith and 5 withthe' inner faces of the cover and the f skirt 7, respectively, in such manner as to constitute a shallow seat. for holding a flat annular gasket 17 that may be made of india rubber or any other yielding material that may be found suitable for sealing purposes.

The'ei'rtent of the uplift of the flange 16 above the face of the cap plate 6 is, for accommodation of the gasket,'made substantially a verylittle in excess of the thickness of the .9

gasket 17. The gasket 17 when introduced into its seat, is held 'in' place by frictional contact between its contiguous surfaces and the walls; 7 of'its seat, andis effectually secured against 9 I angle to each other.-

accidental displacement in use by overhang of the flange 16. At the same time, it is vention relates independently to the relative construction ofthe latch member 15, itself. That member comprehends an elementpreferably made of resilient wire, which, as already specified, is provided with legs 13 and 14 that are fastened to and incorporated with the cap plate 6 of the cover. Said wire element is shaped, as by bending, so as to presenton one side of the cover a loop handle 18, and on the opposite side of the cover to provide resilient terminals 19 and 20 which extend, one towards the other, from vertical deflections 21 and 22 formed at the ends of the: respective legs 13' and 14, as by perma nent flexure imparted to the resilient material of which each leg is formed.

The terminals 19 and 20, as shown in Figures I, II, VII and IX of the drawings, extend upwardly from the endsyof the deflections 21 and 22, respectively, as clearly shown in Figure VII, and, in specified assemblage with the container, exert a spring pressure against the retaining ledge 4 in a downward direction and also, by virtue of their lateral deflection, exert at the same time a rearward lateral pressure against the neck 3 when the cap plate 6 is set in operative position to fit over the rim2. The efiect of the composite forces exerted by the specified member 15 is to pull, the cover towards therim 2, and, at the same time, in'a direction away from the hall'- dle 18, with the result of promoting the latch ing function of the v member 15, as hereinafter specified. 1 3 Y iIn lieu of the upwarddeflection of the terminals 19 and 20, the same purpose may be accomplished, with perhaps better results, by

substituting the angularly disposed ledge/5 for the ledge 4, for cooperative engagement with coaxial spring terminals 23 and 24, as shown in Figures VIII and X, instead. of the terminals 19 a'nd 20 that are disposed at an In the construction shown in the figures last named,the resilientterminals 23 and 24 7 yield by their'engagement with the ledge 5, so

as to effect the result of a downward and backward pull upon thecover described in the 'last and in the next following paragraphs,

the ledge 5 acting against the terminals 23 and24 after the manner of a wedge to compel movement in two directions of the cover'upon the container when the'cover and-container are in cooperative assemblage.

. a In respect to the, function :just indicated,

the'handle 18 is, in assembled position, dis- .-posed, on theopposite sideofthe'rim2 from the terminals 19 and 20, or the terminals '23 and 24, whichever be employed, and is, by the conformation of the wire of which the member 15 is made, provided with resilient latches 25 and 26 having cam-acting sloping top faces that are con 0ined by the interposition of the loop handle 18 between them. Now,

if the cap plate 6 of the cover, assembled substantially as specified with the member 15, is properly adjusted and pressed down upon and against the top of the rim 2, the skirt 7 of the cover will, by its engagement with the outer perimeter of the rim, direct the movement of the cover so that continued pressure thereupon will cause the resilient terminals 19 and 20, or 23 and 24, of the latch member 15 to yield laterally until they slip over the rim 2 and then make effectual engagement with the bottom of the retaining ledge 4 or of the ledge 5, as the case may be. Afterwards, by cooperation therewith, they will exert a spring action between the cover and the rim 2 V which will tend to draw one side of the cover towards the body 1 and toeffect thereby,closure at the adjacent portion of the gasket'l'? against the top of the rim. At the same time, the inward inclination of the terminals 19 and 20, acting in addition to their said upward in clination, will cause their resiliency to exert,

on the diametrically opposite side of the gasket from that last indicated, a pull on the member 15 to compel latching engagement of contact between the rim and the superposed V gasket; but theemployment of the bead is not indispensable. Thebead 27, when em ployed, may be disposed on the top of the rim 2, which may be of any preferred contour in cross-section, but I prefer in that regard, to 4 lar 29, confined tautly about the neck .3. The

collar 29 terminates at its opposite ends in loops 30 adapted for reception of the termi- .nals 19 and 20, or 23 and'24, respectively, and

thus serves to secure the cover to the collar, and through it to the container. V

The securing of the cap plate 6 to the neck 3 by aid of the, collar 29" not onlyefl'ects a desirably simple hinge relationship between the cover and the container, but also the resiliency of the terminals 19 and 20, acting against the ledge 4:, or of the terminals 23 and 24 acting against the ledge 5, when fastened to the collar 29, produces a composite spring action which servesto normally support the cover in the open position as shown in Figure I. It is for this reason that the subject matter illustrated'in that figure is preferred because it is of a most highly organized and eflicient type. v

A distinctive feature of my closure may be defined to be the provision therein of means for obtaining the application of such spring pressure at opposite sides of the container as will tend to compel uniformity of sealing engagement between the gasket 17 and the top of the rim 2 against which the gasket makes contact. The lateral resiliency of the terminals 19 and 20 serves to insure that result by the proper functioning of the latches 25 and 26 against the retaining face of the ledge 4.

It may be further observed that the employment of the gasket is not indispensible, and may be omitted in the manufacture of a cheap form of container in which closure to air tight degree between the container and cover is not a desideratum.

What I claim is:

1. The combination with a container body having a continuous annular latch-member retaining ledge formed upon a mouth-defining rim for the container, of a cover having a yielding gasket and a latch member extending across it and provided at one end with two separate resilient ledge-engagin members extending toward each other, an

at the opposite end with cam acting resilient ledge-engaging latches, said oppositely extending resilient member being hingedly secured to the container body by a collar confined to a neck formed therein below said rim.

.2. The combination with a container body having a continuous annular latchemember retaining ledge formed upon a mouth-defining rim for the container, of a cover having a yielding gasket and a latch member extendof said member, said resilient members being disposable, respectively, in dilferent planes for the purpose of securing for the cover, when applied to a container, spring 'pressure in transverse and lateral directions, substantially for the purpose specified.

4. A container cover having a yielding gasket and a latch member extending across it, in combination with cam-acting latches disposed below the cover at one end of said member and oppositely extending resilient members at the other end of said member, said resilient members being disposable, re-

spectively, in difierent planes for the purpose of securing for the cover spring pressure in two directions, substantially for the purpose specified, said latches being also resilient for effecting in them the cam action desired.

5. A container cover having a disc-shaped cap plate and a peripheral skirt, made of thin metal and provided with a reinforcing plate united to the cap plate to lend stiffness to it, the upper reinforcing plate. being provided with infolds adapted to secure in place a latch member provided on the cap plate.

6. A container cover in combination with v a disc-shaped cap plate and a peripheral sklrt thereon, the cover being made of thin metal and provided on opposite sides with reinforcing plates united to the cap plate to lend stiffness to it, the reinforcing plate inside the cap being circular and provided with an upstanding annular flange forming with the skirt an annular gasket seat, and a yielding gasket removably confined within said seat by engagement with said flange and skirt.
